I recently had the same problem as did many others as demonstrated by the numerous post on these forums. I troubleshot by by turning off everything but the game. this will require you to do what is known as a clean start. If the game functions properly start bringing up individual programs until you discover the cause or, as in my case, it continues to work when you have only that which you need. Only have what you absolutely need in the start up menu. A number of programs that were initiated originally handled by Startup I now run manually. I believe this is where my compatibility problems. I also recommend that you disable any overlays that you have running. Despite what people will tell you this is not a hardware issue. Good luck.
